NSHXAFÖ 1.8/3kV Halogen-Free Rubber Cable

NSHXAFÖ Cable for Railway Vehicles and Equipment Wiring

NSHXAFÖ cable is a 1.8/3 kV single-core halogen-free rubber cable for trains, trams, buses, cars, industrial clutch equipment and distribution systems up to 1 kV. It is designed for installations where flexible copper conductors, rubber insulation and low-smoke halogen-free sheath materials are required in a compact black cable.

The supplied construction uses an IEC 60228 Class 5 multi-stranded annealed copper conductor, extruded 3GI3 rubber insulation and an HM3 halogen-free rubber outer sheath according to DIN VDE 0207 Part 24. This makes the cable relevant where installers need a flexible single-core cable with fire-performance and smoke-material references rather than a standard PVC-insulated wire.

For procurement, NSHXAFÖ should be selected by conductor size, current load, bending radius, installation temperature, fire-performance requirement and vehicle or equipment documentation needs. It should not be marketed as a general outdoor trailing cable unless the specific installation conditions are reviewed.

Key Engineering Features

• Halogen-free rubber sheath: The HM3 outer sheath supports installations where halogen-free materials and smoke behavior are part of the specification, such as rail and public-transport equipment.
• Flexible Class 5 copper conductor: Multi-stranded annealed copper improves routing flexibility compared with rigid conductors, useful in vehicle wiring and compact equipment paths.
• 3GI3 rubber insulation: The extruded rubber insulation provides a robust electrical layer for 1.8/3 kV cable construction and 90°C maximum operating temperature.
• Vehicle and equipment focus: The supplied application targets trains, trams, buses, cars, industrial clutch equipment and distribution up to 1 kV, which helps distinguish this cable from ordinary building wire.
• Defined bending guidance: Bending radius is listed as 6 × D for fixed/fast makes and 10 × D for flexible makes, supporting practical routing checks before installation.
• Fire and smoke references: IEC 60332-1-2, EN 50267-1 and IEC 61034-1-2 are listed in the supplied data, covering single-cable flame propagation, halogen-free material and smoke density references.
• Clear size/current table: Available data covers 1 × 1.5 mm² to 1 × 70 mm² with diameter, weight and maximum current load in air.

Standards and Compliance

The standards above are reproduced from the supplied technical image. Project-specific railway, vehicle, rolling-stock or national approvals should be confirmed with the final quotation and documents.

Dimensions and Electrical Data

The table below supports conductor size selection, cable-entry checks, routing space and current comparison. Final current capacity should be verified against installation method, grouping, ambient temperature and project standard.

Applications

• Electrical installations in trains and trams
• Bus and vehicle wiring routes requiring halogen-free rubber cable
• Industrial clutch equipment wiring
• Distribution systems up to 1 kV where a 1.8/3 kV cable family is specified
• Equipment wiring where flame propagation, halogen-free material and smoke density references matter

Selection Notes for Buyers

Select the conductor size from load current, voltage drop, short-circuit requirement, routing space and termination hardware. The supplied table gives maximum current load in air, but the actual rating can change with grouping, enclosure temperature, cable tray arrangement and vehicle installation conditions.

For railway and vehicle projects, confirm whether the listed standards are sufficient for the project or whether additional rolling-stock fire, smoke, toxicity, vibration or national approvals are required. Do not treat a material standard as a complete vehicle approval.

Check bending radius during design. Use 6 × D for fixed or fast-make routes and 10 × D for flexible makes. Tight bends around equipment frames, cable ducts or gland plates can reduce service life even when the electrical rating is correct.

If the cable is used for distribution up to 1 kV, verify the installation protection, earthing arrangement, conductor color/marking requirements and the interaction with adjacent cables. NSHXAFÖ is a single-core product, so phase grouping and magnetic effects should be considered for high-current routes.

Why Choose Tebaoflex

Tebaoflex supports industrial and vehicle cable projects with conductor-size review, application matching, sheath marking, packing, OEM cable printing and export documentation. For NSHXAFÖ enquiries, we can compare the requested size, current, cable diameter and bending space against the customer’s drawing before quotation.
